SKA Gorwihl Wastewater Treatment Plant, Rüßwihl, Baden-Württemberg, Germany

SKA Gorwihl is a former wastewater treatment plant located in Rüßwihl, a district of Görwihl in the Waldshut district of Baden-Württemberg, Germany. The plant served a population of 1,600 and was designed with a capacity of 2,500 cubic meters per day, with an average discharge volume of 600.16 cubic meters per day. The facility is now closed. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 in freshwater areas, and Germany implements this through national legislation. Although the plant is closed, the regulatory framework ensures that wastewater from the area is now likely treated at a nearby facility meeting similar standards. The plant's discharge entered the local watershed, which ultimately drains into the Rhine River via the Murg and Hochrhein systems. The Rhine is a major European waterway supporting diverse aquatic life and providing drinking water for millions. More efficient facility, reducing local discharge points and improving overall water quality in the region.

The plant's discharge contributed to the local tributaries of the Rhine River, which flows through the Upper Rhine Valley and eventually into the North Sea. The Rhine basin supports a wide range of aquatic species, including migratory fish such as salmon and eel. The region's water quality is managed under the EU Water Framework Directive, which aims to achieve good ecological status for all water bodies. The closure of this plant likely reduces local nutrient and pollutant loads, benefiting downstream ecosystems.
